In an isolated village of the Alentejo region, a conflict arises. José Vitorino, one of the landowners of the region, rich in prehistoric monuments, wants to build a luxurious solarium in lands filled with ancient rocks, places of devotion and sacred rituals. Indifferent to the people’s protest, who believe in the magical powers of the stones and that the region’s drought is due to the rocks’ destruction, José Vitorino hires an architect to plan his new house. On christmas eve, in the middle of the winter solstice, a strange ceremony around a dolmen, once an altar for bloody sacrifices in more remote times, releases a harmful spell. A race against time to reverse the faulty charm begins.
